INDIANAPOLIS (AP) — Indiana’s state superintendent announced Friday she is seeking at least $614,000 in damages from CTB/McGraw-Hill for testing troubles as the company’s president apologized to state lawmakers.

CTB/McGraw-Hill President Ellen Haley called the disruptions for nearly 80,000 Indiana students last month “unacceptable” Friday and said the company’s online servers were “overwhelmed.” A spokesman said Haley would answer questions about the damages after she finishes testifying in front of the joint House and Senate education committee.

Superintendent Glenda Ritz said she is seeking $400,000 for fines covered in the company’s $95 million contract with the state. The additional money would pay for an independent review of the testing data, as well as better reporting data.

Administration of the state’s standardized test was thrown into chaos after online tests began freezing for hours at a time. The results are used to calculate teacher pay and school grades.
